I wouldn't notice 100g off my cranks. But I'd totally notice it off the seat when I stood on the bike. Or 100g less in the tyres should be noticeable. And I'd notice it off the bars without even standing up, but how much depends how long the stem is.

Of course, it's 'only' of psychological benefit unless you're climbing. Quicker wheels need more work to keep at speed, etc.

But a whole lot of folks here are dismissing the placebo effect out of hand. People conducting scientific studies don't.

I already made appoint about theoretical advantages, by mentioning products being tested in a perfect world. A more aero bike will slice through air easier and therefore be faster, same for wheels, helmets..bla bla bla

I got two bikes. One is 17 pounds and one is 15 pounds. I am equally fast on both of them overall. 17 pound bike is more aero, while the 15 pound bike is more stiffer and ideal for climbing. Depending on the type of ride I am doing more or less hills and various conditions, I will have to work harder with the 17 pound bike, but again, that does not mean that I am guaranteed to be dropped out of a ride. It only means that I have to work harder. Every ride that I do, I can assure you that I will complete unless I am seriously out advantaged in physical fitness, which has not yet happened yet. I certainly hope it does at some point, because I love being challenged by faster people. That is the way I get faster.

When it comes to 100 grams (PER TOPIC) and noticing the difference. I can say from "My experience" that it is negligible. People buy into all the advertisements of speed and aero and bla bla bla..that they forget, on a day to day rides whether it be solo or group, so many factors play into affect. Just a few examples. Taking brakes. Getting caught at traffic light, accidentally shifting into a wrong gear, or being in a wrong gear and wasting more watts. Being on the top bars instead of drops, having two water bottles when only needing one. Having more spare parts than needed..I can go on. Those are the real world factors and they cancel out any advantage 100g could save you.

Hell, even armature racers during a race will not have a support vehicle, so they have to rely on themselves. What they pack for that race will determine how much extra weight they pack on.

At the end of the day, is 100g less better for performance...yes. Will I personally notice it, more than likely not. Is 100g weight savings worth whatever price tag comes with it? That is up to you! I personally only buy more expensive and lighter stuff if what I currently own is in need of replacement. I would not just buy something lighter just to have something lighter.

Doesn't really have anything to do with completing or not completing a ride, or getting dropped on a ride. It is not an either/or situation. You can still push yourself, AND push the limits of technology on the bike. The faster bike will make you faster, whether or not you're in shape or not in shape.

And wrong, even Cat 4 and 5 races have wheel trucks/support vehicles and feed zones. Zero reason to carry anything extra.

Have you actually ever pinned on a number?

Elvir

Sounds like you are agreeing with my last statement. Seems that you and I have difference in opinion in what 100g means to us.

rubiksoval

Sure, your last statement, I do. But my initial disagreement centers on your premise that you're going to make up for having an "inferior" bike by simply riding harder.

That's an erroneous thought process when it comes to cycling.

Elvir

Were not talking about "Inferior" bikes. Were talking about 100g, which by the way has not even been established what that is. My next bike experience that I want is a Trek Madone. The one I want is 17lbs compared to my trek emonda at 15lbs. My emonda is not even close to being an aero bike, but weight disadvantage on the madone of 900g would not make it inferior, especially since its designed to be much faster.

We can really go on and on..at the end of the day I am expressing my opinion and you are getting way too bent out of shape about it.

Define big. If you're racing and a few seconds or watts is a big deal, then yes, they will make a difference. If you just ride your bike to the coffee shop and do the occasional group ride, it won't be a very big difference.

rubiksoval

That's why "inferior" was in quotation marks. To denote a difference in the two bikes, in this specific case, in weight. It's a bit of hyperbole, but the point should be fairly obvious.

At the end of the day you're making errant comments about something you don't quite seem to understand, and you're broaching subjects with which you apparently have no experience. I'm not bent out of shape about it, I'm just pointing that out.

Elvir

sure, lets go with that.

BlazingPedals

If you can accumulate many 100-gram savings, the results might become noticeable. But just 100 grams all by itself? Nope, no change.

Kimmo 

It depends where.

If I added 100g to your belly, you wouldn't notice. But what if I added it to your nose?

I just want to climb Mt.Washington someday.

Just leave it alone and lose a few pounds.

Racing Dan

Assuming you are a fast climber that can do 1000m in one hour, adding 0.1kg will add less than 10 (more like 5) seconds to your accent, or require an additional ~0.3W to the grand total of about 285W (assuming 200lbs total weight) to maintain same accent time. > +0.1kg is insignificant outside the scope of racing for money. > Go for better aero an less rolling and drive train friction, if you want to go faster.

I thought it was living in the country that added seconds to your accent
